INRICHTING VOOR HET METEN VAN BLOEDSTROOMSNELHEID.

摘要

A computer adjunct for use with an impedance plethysmograph which provides signals related to impedance in a biological segment. Circuit means are included for converting the pulsatile plethysmograph signals to average DC levels and for combining them to provide a signal related to blood hydraulic-flow rate through the biological segment. An adjustable amplifier is provided within the computer for interposing a signal having a predetermined value for providing a normalized signal related to flow rate per volumetric unit of the biological segment. The combination is capable of such measurements for calf segments or thoracic segments.
